A IELECTR'IQ-LIGHTFIXTURE;

forming part of letters I SPECIFICATION atent No. 530,343, datedDecember 4,1894.

Application filed May 24.1e9 1," are No. 512,284. (N5 model.)

To all whom it may concern.-

Be it known that I, HERMAN HoRN, a citi-i zen of the United States,residing in the city and county of Philadelphia, State of Pennsyl-Vania, have invented a new and useful Improvement in Electric-LightFixtures, which I mprovement is fully set forth in thefollowmgspecification and accompanying drawings. My nvention consists ofimprovements in electric light fixtures, which are more espe, ciallydesigned to support a cluster of lights, the same being made 'ofseparable parts, whereby the light-supporting part, is convenient forremoval, and the necessity forcutting the wires is avoided, the saidparts being also readily replaceable without reu'n'i ting the wires, andprovision is madefor readily replacing a broken shade, orformaking'other slrnple repairs without the] assistancefof a skilledelectrician, all 'aswill be hereinafter setforth.

Figure 1 represents a side elevation of an electric light fixture,having a portion broken away, embodying my invention. Fig. 2 representsa bottom plan view of a portion of the stationary part of the same. Fig.3 represents a section on line as, to, Fig. 2. Fig; 4 represents a planview of the lower socket of the fixture, and Fig. 5 representsaplan viewof the reflector, showing the lamp sockets in position.

Similar letters of reference indicate corresponding parts in the severalfigures. Referring to the drawings: A designates a hollow stem, theupper extremity of which is adapted to be suitably secured to anydesired point, preferably the ceiling of a room. B designates a rosettefor the top of the stem. C designates a holder for the shade D, thelatter being held in place by means of the screws E. A

To the lower end of the stem A is suitably secured the, hollow head F,the open end of which is closed by a disk of porcelain G, which is heldinplace by the screws H, the heads of which have another function to behereinafter described.

To the outer portion of the porcelain disk G, are secured the brassplates J and K, by

and serveto conductthe electriccurrent to the said contact plate .Laport-ion Not which is ofi-set, and is provided with the slightprojection P. The plate K assists in holding fthe plate J against thedisk G, the binding screw L and the screw Q a passing through preferablyin a recess B in the disk G. The plates J are two in number, as are alsothe Wires M and the binding screws L, Fig. 3.

which is suitably attached the inverted cone shaped reflector T, whichis preferably corrugated and also serves as a lamp holder,

S and also the lamp socketsB and the electrical connectionstherebetween, the rings or bushings U assisting to hold the lamp socketsin position and to give the fixtures a finished appearance.

; ,Theup'per'portion of the socket S is provided with a porcelain diskV, which is held in place by the-screws W, W, and has also the off-setcontact plates X, which are provided with the holes Y, which receive theprojections P, when the said parts are placedin juxtaposition, theplates Xbeing held in place and being provided with wires andbindi'ngscrews, &c., in all respects similar to the construction shown in Fig.3, said plates being somewhat elastic.

the top of the socket S, and A designates slots l therein, diametricallyopposite each other, which are adapted to receive, and serve as a guidefor the heads of the screws H.

The operation will now be apparent. i Assuming the parts to be in theposition shown, suppose for any reason it is desired to take the fixtureapart, the socket Sis turned until the heads of the screws in the fixed,portion contact pieces N being disengaged from the holes Y by thismovement, and a pull downward separates the light-supporting part fromthe stem A, and a new shade may be placed out cutting any of the wiresor, the employmeans of the binding screws L, the heads of which are insuitable contact with the wires M,

ment of skilled labor. To put the fixture together, the parts are placedin juxtaposition,

F reach the slots A,'the projections P on the in position, or repairsmade if desired, withfwhich pass downwardly through the stem A,

both plates, the head of the screw Q resting S designates the socket ofthe fixture, to

said reflector serving toconceal said socket Z designates an annularenlargement near as above described, and turned till the projections Penter the holes Y, when the circuit is completed.

It will be evident that the number of lamps may be increased ordiminished, and that the reflector may be secured to the socket S in anysuitable manner. Within the reflector T are secured the electric lampsockets B, the same thus being concealed from view from the outside,leaving only the light-giving lamps exposed to the reflecting power ofthe shade and reflector, thus increasing the volume of light andavoiding the formation of shadows.

It is obvious that the reflectorT may be of various shapes other thancone-shaped, as shown and it is also evident that other changes may bemade by those skilled in the art which will be within the scope of myinvention and I do not therefore desire to be limited to the exactconstructions I have herein shown and described.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is.-

1. A stem, one end of which is adapted to be secured to some fixedpoint, the other end of which is detachably secured to a socket S thelatter carrying a reflector which serves to support and conceal withinitself the lamp sockets B and the electrical connections therefrom tosaid socket S, the above parts being combined substantially asdescribed.

2. A stem having a hollow head, a disk secured therein, contact platessecured thereto, said plates being adapted to engage other contactplates secured to a similar disk in a socket, the latter being separablefrom the stem and being adapted to supporta reflector which also servesto support lamp sockets and.

electrical connections thereto, said parts being combined substantiallyas described.

3. A stem, a hollow head thereon, a disk secured therein, contact platesJ suitably secured to said disk, said plates having studs or projections 1 a socket S having also a disk and err-set contact plates, thelatter having openings to.receive said projections P, a reflectorsuitably attached to said socket, said reflector being adapted to serveas a support for electric lamps, and means for guiding and holding saidsocket in place, substantially as and for the purpose set forth.

4. A sectional electric light fixture having contact devices, andadapted to support several lamps, a removable socket portion having areflector secured thereto, which is common to all of said lamps, andelectrical connections supported by said socket within said reflector,said parts being combined substantially as described.

5. An electric light fixture having a part adapted to be held stationaryin position, and a shade connected with said part, and another partremovably connected with the former the removable part being providedwith an inverted cone shaped reflector, and one or more electric lampsattached to the latter, said parts being combined substantially asdescribed.

6. A sectional electric light fixture having a supporting device, anopen top reflector secured to said supporting device, lamp socketsattached to the interior of said reflector, and electrical connectionsthereto, concealed by said reflector, the latter also concealing saidsockets, said parts being combined substantially as described.

-7. In a sectional electric light fixture, an immovable portion adaptedto support a shade, and another portion removably connected with theformer, said removable part being provided with an open top reflector,the latter being adapted to support and conceal lamp sockets,substantially as described.
